MGS-408 Gas Detection Controller

Part number: 6702-8000

8-Channel controller for refrigerant, toxic and combustible gas detection

Bacharach’s MGS-408 Gas Detection Controller centralizes the status of up to 8 gas detection channels in a single location. The digital display provides a real-time view of the gas concentration and status at each gas detection point. It also allows for the controller to be configured in minutes vie the intuitive menu system. A bank of LEDs corresponds to each connected gas detector; showing power, alarm status and fault indicators.

The MGS-408 can provide power for up to 8 gas detectors, which can be daisy-chained along with Modbus communication to each gas detector; simplifying and reducing the cost of installation. Integration is possible with Bacharach’s MGS-400 series, MGS-250 and MGS-550 Gas Detector platforms; allowing for a flexible gas detection system design which can utilize the benefits of multiple gas detector types as required in different locations (machinery rooms, cold storage rooms, walk-in freezers and food preparation areas).

Combining the MGS-408 with Bacharach’s range of gas detectors provides a single system with an easy means of achieving compliance with refrigeration safety standards such as EN 378 and ASHRAE 15.

  • Centralized power and communications for up-to eight connected gas sensors, including the MGS-250, MGS-410, MGS-450, MGS-460 and MGS-550
  • Digital display shows real-time concentration readings for all connected gas detectors and makes configuration and self-diagnostics intuitive
  • Tri-color LED indicators provide “at-a-glance” system / alarm status
  • Integrated SD card retains the alarm / status history of the gas detection system
  • Modbus communications (slave) for integration with third-party BMS / BAS control systems
  • Three user-configurable relays (fault, low and high alarm) may be used to activate external beacons / sounders, ventilation or other countermeasures
  • Integrated audible / visual alarms with push button silence for refrigeration safety compliance – no additional hardware
